The present invention pertains to a process and to a device for printing a multicolor image composed of at least two varicolored partial images on a surface. A first partial image is transferred onto the surface in an ink transfer position and at least a second partial image is transferred onto the surface in the same ink transfer position and is superimposed to the first partial image. The partial images transferred onto the surface are dried at least partially or hardened at least partially between the ink transfer steps. The drying step is carried out according to the present invention in the ink transfer position. High print quality can be achieved according to the present invention in a simple manner because the first partial image set and dried partially or also the respective additional, partially dried partial images always have well-defined surface properties. Essentially cylindrical bodies are preferably printed in multiple colors according to the present invention.
